My Vercel Sandbox session shows Stopped in the dashboard, and the session record reports persistent: false. Vercel Agent explained that microVM teardown and ephemeral storage cleanup are expected when a non-persistent session stops. I’d like to verify cleanup for this specific session.

Is there a customer-visible event, API field, or dashboard entry that confirms both microVM teardown and ephemeral storage cleanup? If there is no separate record, is Stopped with persistent: false the strongest evidence available to customers?
